MIPS: Netlogic: select MIPSR2 for XLP
This allows us to use the r2 optimized code from kernel headers while compilation. Disable PGD_C0_CONTEXT option for XLP, which does not work. Signed-off-by: Jayachandran C <jchandra@broadcom.com> Patchwork: http://patchwork.linux-mips.org/patch/4456 Signed-off-by: John Crispin <blogic@openwrt.org>
